CDCLVP1204RGTR Four LVPECL Output, High-Performance Clock Buffer VQFN16 spot stock

Product Descriptions

The CDCLVP1204 is a highly versatile, low additive jitter buffer that can generate four copies of LVPECL clock outputs from one of two selectable LVPECL, LVDS,    or   LVCMOS inputs  for   a  variety  of communication applications. It has a maximum clock frequency up to 2 GHz. The CDCLVP1204 features an on-chip multiplexer (MUX) for selecting one of two inputs that can be easily configured solely through a control      terminal.     The  overall      additive  jitter performance is less than 0.1 ps, RMS from 10 kHz to20 MHz, and overall output skew is as low as 15 ps, making the device a perfect   choice for  use in demanding applications.

The CDCLVP1204 clock buffer distributes one of two selectable clock inputs (IN0,  IN1) to four pairs of differential LVPECL clock outputs (OUT0, OUT3) with minimum skew  for    clock   distribution.     The CDCLVP1204 can accept two clock sources into an input multiplexer. The inputs can be LVPECL, LVDS, or LVCMOS/LVTTL.

The CDCLVP1204 is specifically designed for driving50-Ωtransmission lines. When driving the inputs in single-ended mode,   the  LVPECL bias  voltage(V_AC_REF) must  be applied to the unused negative input terminal. However, for high-speed performance up  to  2  GHz,    differential     mode  is  strongly recommended.

The CDCLVP1204 is characterized for operation from–40°C to +85°C.
